Aims:
The rise in one-person households is a global trend. We aimed to investigate mortality risk in individuals with diabetes living alone (IDLA) using a large-scale population-based database.
Methods:
A total of 2,447,557 adults with type 2 diabetes were identified from the Korean National Health Information Database. One-person households were defined based on the number of registered family members. The risks of all-cause and cause-specific mortalities were estimated using a multivariable Cox proportional hazards regression model.
Results:
During a median follow-up period of 6.0 years, 191,084 deaths (7.8 %) occurred. IDLA had a higher risk of mortality compared to those not living alone after adjusting for potential confounders (HR 1.20, 95 % CI: 1.18-1.22). This association was more prominent in younger individuals, men, and those with low income, and it was dependent on the duration of living alone. The risks of cause-specific mortality were all significantly higher in the IDLA group compared with the non-IDLA group. Adherence to favorable lifestyle behaviors was associated with a significant reduction in all-cause mortality, particularly in IDLA.
Conclusions:
The elevated risk of mortality in IDLA highlights the need for tailored medical interventions and social assistance, particularly for those with unhealthy lifestyles or low income.
